I’m new to Spring Boot. I am doing JWT authentication. When I register a new user, the database somehow stores the wrong encoding. Can you help me?

it registers user and creates token, but when i try to log in, it says invalid password

here is my code:

@Bean
public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
    return http
            .cors(withDefaults())
            .csrf(AbstractHttpConfigurer::disable)
            .authorizeHttpRequests(
                    req->req.requestMatchers("/login/**", "register/**")
                            .permitAll()
                            .anyRequest()
                            .authenticated()
            )
            .userDetailsService(userDetailsServiceimpl)
            .exceptionHandling(e->e.accessDeniedHandler(accessDeniedHandler)
                    .authenticationEntryPoint(new HttpStatusEntryPoint(HttpStatus.UNAUTHORIZED))
            )
            .sessionManagement(session->session
                    .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            )
            .addFilterBefore(jwtAuthenticationFilter, UsernamePasswordAuthenticationFilter.class)
            .build();
    }

@Bean
public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
}

public AuthenticationResponse authenticate(User request) {
    User user = userRepo.findByEmail(request.getEmail())
            .orElseThrow(() -> new IllegalArgumentException("User not found"));

    System.out.println("Raw Password: " + request.getPassword());
    System.out.println("Stored Encoded Password: " + user.getPassword());

    if (!passwordEncoder.matches(request.getPassword(), user.getPassword())) {
        throw new IllegalArgumentException("Invalid password");
    }

    String token = jwtService.generateToken(user);
    return new AuthenticationResponse(token);
}
